You don't have to like him if he is closing out wins. Trust me, in a dugout they have guys on their own team they don't like but love because they get the job done.
On MLB radio, I heard there was a memo put out to teams in 2010 specifically banning this sort of thing. At first i thought no big deal and I continue to think about it I have pushed more extreme and call for a post season ban.
Does a September call up count towards their mlb service year? For example if they called up Vlad, which they won't, does that start his MLB time? I'm sure the Jays want to delay that start as much as they can similar to how the Cubs did Bryant.
